Whereas past clipshave focused on Clark Kent's heroic instincts as a kid and his transition to wearing the "S" on his chest, the newest trailer for the Warner Bros. release is all about his powerful foe, General Zod.

"I have journeyed across an ocean of stars to reach you," says Michael Shannon as his villainous character, who issues a warning to Earth's population. "Your world has sheltered one of my citizens. He will look like you, but he is not one of you. To those of you who know of his location, the fate of your planet rests in your hands. To Kal-El, I say this: surrender within 24 hours, or watch this world suffer the consequences."
